Notes to the characteristics
1. Signal with the negative-going sync; amplitude includes sync pulse amplitude.
2. Indicated is a signal with 75% colour bar, so the chrominance-to-burst ratio is 2.2 : 1.
3. Nominal contrast is specified as the maximum contrast 5 dB and nominal saturation as maximum 6 dB. This figure
4. Cross coupling is measured under the following condition: input signal nominal, contrast and saturation such that
5. The signal-to-noise ratio is defined as peak-to-peak signal with respect to RMS noise.
6. All frequency variations are referenced to the 4.4 MHz carrier frequency. All oscillator specifications have been
7. The change in burst with V
